LibreOffice is a feature-rich, open-sourced office productive suite and is one of the critical parts of Linux desktop like openSUSE.
Consumer products, like LibreOffice, have to keep continuous evolve to catch end-users' desire than server-side software which is preferred to be more stable than features added. Thus, LibreOffice takes time-based release policy of performing major release with functional additions every six months.
Sometimes you may want to use newer LibreOffice (includes daily build or beta/RC testing build) than pre-packaged version shipped with openSUSE Leap 15 (Leap 15 provides latest "Fresh" LibreOffice 6.0 at the moment (June), but 6.1 will be released August). Of course, you can use TDF build RPM package instead of openSUSE package, but you can do this quickly with modern packaging systems, like Flatpak, AppImage or Snap. Additionally, you can also use several versions parallelly with them.
In this talk, I would like to introduce these ways and pros/cons of the packaging systems on openSUSE Leap 15.
